Gearcase Lubrication

When adding or changing gearcase lubricant, visually check for

the presence of water in the lubricant. If water is present, it may

have settled to the bottom and will drain out prior to the lubricant,

or it may be mixed with the lubricant, giving it a milky colored

appearance. If water is noticed, have the gearcase checked by

your dealer. Water in the lubricant may result in premature bearing

failure or, in freezing temperatures, will turn to ice and damage the

gearcase.

Examine the drained gearcase lubricant for metal particles. A small

amount of metal particles indicates normal gear wear. An

excessive amount of metal filings or larger particles (chips) may

indicate abnormal gear wear and should be checked by an

authorized dealer.

DRAINING GEARCASE

1. Place outboard in a vertical operating position.

2. Remove propeller. Refer to Propeller Replacement.

3. Place drain pan below outboard.
